1100cc - C63/E63 AMG M156 6.3

Finally got around to installing these on my E63, and the 1100cc flow is exactly what I needed to support the cam and header setup. The direct fitment saved me a lot of hassle compared to the usual conversion headaches.

Swapped out my factory injectors for this matched set of eight and the car idles smoother than it ever has. The vehicle-specific fitment meant zero fuss getting them seated on the M156, which I really appreciated.

The 1100cc set dropped right into my M156 with zero fitment issues, and the car feels noticeably stronger up top. I’ve only put a few hundred miles on them, but idle is smooth and no check engine light.
